Zingaphi iidigries ngu-Peechrees olungeleleneyo kumaqondo obushushu aphezulu kwaye zingaphi iidigri ixesha elide lokusebenzisa ixesha elide? Leliphi iqondo lobushushu liphezulu?

Impahla ye-Pekk isebenza kakhulu kwi-Thermoplastic ephezulu ye-thermoplastic ngokuxhaphaza kobushushu obuphezulu, uzinzo lwamachiza kunye neepropathi zoomatshini, kwaye iqondo lobushushu linempembelelo enkulu kumalungiselelo ezinto eziphezulu.

Okokuqala, amaqondo obushushu anempembelelo ebalulekileyo kwinkqubo yokunyibilika kunye nokuqina kwezinto eziphezulu. Ngokubanzi, ubushushu obunyibiliza wezixhobo ze-Peks ngama-343 ° C kunye neqondo lobushushu lingama-315 ° C. Ukuba iqondo lobushushu liphantsi kakhulu, izinto ze-PEEki azinakunyibilikiswa ngokupheleleyo, ezichaphazela iipropathi zendlela yokusebenza kunye nokusebenza kwayo. Ukuba iqondo lobushushu liphezulu kakhulu, impahla ye-Peks iya kukhula kwaye ibole, ngaloo ndlela kuncitshiswa iipropathi zoomatshini kunye nokuzinza kwamachiza.

Okwesibini, iqondo lobushushu likwanegalelo elibonakalayo kuzinzo lwe-suve zezinto eziphakamileyo. Xa izixhobo ze-Peek ziphantsi kwamaqondo obushushu aphezulu, ukonakaliswa kwenkani kunokubakho, kukhokelela ekunciphiseni, ukutshintsha kotshintsho, kunye nezinye iingxaki. Ke ngoko, ngexesha lokulungiswa kwezixhobo ze-Pek, kufuneka kuthathelwe ingqalelo ukulawula ubushushu kwaye kuthintele ukuba wonakaliswe kukugxeka.

Okokugqibela, iqondo lobushushu linegalelo elibonakalayo ekuguqulweni kwezinto eziphezulu zezinto. Ngokubanzi, i-Peks igcwaliswe kwaye iguqulwe ukunciphisa iindleko zabo kwaye kuphuculwe ukusebenza kwabo. Ulungelelwaniso lwe-filler luhlala lufuneka lwenziwe kubushushu obuthile ukuqinisekisa ukuxuba okugqibelele kunye nokuphendula kwezixhobo zefilitha kunye nezinto zeplanga. Ke ngoko, ukulawulwa kweqondo lobushushu kuyadingeka ngexesha lenkqubo yokuhlengahlengiswa ngokupheleleyo ukuqinisekisa ukuphendula okwaneleyo kunye nokusasazwa okungafaniyo kwezinto ezibonakalayo kunye nezinto zeplanga.

Ngamafutshane, amaqondo obushushu anefuthe elibonakalayo kwilungiselelo, ukusebenza, kunye nokugcwalisa ukutshintsha kwezinto eziphantsi. Ngexesha lokulungiselela nokusetyenziswa kwezixhobo ze-Peks, ulawulo oluchanekileyo lwamaqondo kufuneka ukuqinisekisa ukusebenza kunye neziphumo zesenzi.

I-Peek sisixhobo se-polymeric sinepropathi enobushushu kakhulu egcina amandla amahle kunye nokuqina kwiindawo ezinamaqondo obushushu aphezulu kwaye yinto esetyenziswa rhoqo kwizicelo zobunjineli obungaphantsi kobushushu obungaphezulu kobushushu. Iqondo lokushisa elisebenzayo lezixhobo ze-Peks lixhomekeke ekuqulunqweni okuthile kwezinto kunye neepropathi zayo zokuzinza ezishushu. Ngokubanzi, izixhobo ze-Pek zinokusetyenziswa kumaqondo obushushu aphakathi kwe-250 ° C kunye ne-300 ° C.

Oku kulandelayo luluhlu lwamaqondo obushushu ngaphandle kohlobo:

1. Izixhobo ze-Prections eziphantsi
2. Izinto eziphuculweyo ze-facring ephantsi: Ukusetyenziswa kobushushu kwi-40 ℃ ukuya +260 ℃
3. Izixhobo ze-Peks ezineProperties ezilungileyo zoMbane: Ukusetyenziswa kobushushu kwi-40 ℃ ukuya +260 ℃

Ingqwalaselo ekhethekileyo ihlawulwe kuluhlu lwamaqondo obushushu ezixhobo ze-Peks ikwachaphazeleka yimeko yezinto ezibonakalayo (isidanga sokuzala, ubungqingqwa, njl.njl. , ekusebenziseni izixhobo ze-PERE, kufuneka kukhethwe ngokweemeko ezithile zemodeli efanelekileyo kunye noluhlu lobushushu, kwaye kuthintele ukugqitha kuluhlu lwamanzi amaqondo okuqinisekisa ukusebenza kunye nokhuseleko
